The key word here is "absurd," because it's a word Limbaugh proudly uses. For years he's described what he does as "demonstrating absurdity by being absurd" -- in fact, the title of a chapter in his first book was "People, Think for Yourselves, Or Demonstrating Absurdity By Being Absurd." In fact, just today he described his sex-video remark about Sandra Fluke as "illustrating absurdity here by being absurd."
Either Santorum knows all this (and as a card-carrying movement conservative, he presumably would) or Santorum in understands that saying this is an easy way to attack Limbaugh without actually attacking him.
Oh, and Limbaugh's an "entertainer," so it's silly for anyone to care, right? (Funny, back in January, when Santorum said "we've lost, unfortunately, our entertainment industry" to "the left," he seemed to regard entertainment as a lot more relevant to politics.)
The entertainer dodge is an out Rush has used before. He'll survive this. He always does. Santorum is calling Rush's comments absurd so that anyone attacking him for it is engaging in even more absurd behavior.
Here's the thing, of course. It's false equivalence to the max, and ABL calls the GOP out on it.
Rush Limbaugh is calling your mothers, sisters, and daughters sluts and prostitutes. “Inappropriate” and “absurd” doesn’t begin to cover it.
And by the way, the “you sluts want us to pay to have sex” narrative is unimaginably stupid. Sandra Fluke testified about her friend who was prescribed birth control for a medical condition — ovarian cysts. Nobody’s asking to be paid to have sex. Nobody’s asking for government-subsidized condoms. Besides, we women have been paying men to have sex for years. The only purpose of Viagra and Cialis and the like is to allow men to have sex. Many health insurance plans cover Viagra. Where’s Rush’s outrage about that? Shouldn’t all men who take those little blue pills be forced post sex tapes online?
